atm: zatm: Fix empty body Clang warnings
[ Upstream commit 64b9d16e2d
]
Clang warns:
drivers/atm/zatm.c:513:7: error: while loop has empty body
[-Werror,-Wempty-body]
zwait;
^
drivers/atm/zatm.c:513:7: note: put the semicolon on a separate line to
silence this warning
Get rid of this warning by using an empty do-while loop. While we're at
it, add parentheses to make it clear that this is a function-like macro.
